Dual polarized antenna decoupling for 60 GHz planar massive MIMO

Millimeter-wave (mm-Wave) Massive Multiple Input Multiple Output (MIMO) at 60 GHz is a candidate of advanced wireless communications for indoor environment. Mm-Wave massive MIMO antenna with lower frequency with sectoring technique has been proposed in previous research. Also dual polarized configuration for MIMO in lower frequency and lower number of antenna. Massive MIMO at 60 GHz mm-Wave is not evaluated yet in these previous research. In this paper, dual polarized mm-Wave massive MIMO has been proposed. Antennas are modeled in circular disk proximity coupled planar array. Bandwidth of dual polarized configuration is 4.349 GHz, wider than 4.303 GHz in single polarized configuration. Envelope Correlation Coefficient (ECC) of dual polarized configuration is 25 times lower compared to single polarized configuration. Dual polarized configuration shows better performance both in bandwidth and ECC compared to single polarized configuration.
